' Application fi1edApri127,1903. SerialNo.154=,4Z0. (Ndmodel-J To aZZwh/cm it may concern: A t Be it known that I, A LAN'G. RUSH, a citize of the United'States of America, residing in the'city of-Los Angeles, in the county of Los Angeles, State of California, have invented certain Improvements in Hydrocarbon-Burm ers, of which the following is aspeeification.

This invention relates to hydrocarbon-burn-- ers, and particularly to-a= burner adapted to volatilize crude or low-grade petroleum-oil burnedf t 3 Thegeneral object of the inventionfis to provide a burner of'this class which will be adapted to burn low grade oil with high efliciency and admix air to the volatilized oil as 'it is andwithout noise and-"to provide for great variation of flame, so that with the same burner a great range-of heat may be secured, the burner being capable of being turned down very low and'then at pleasure increased to f full capacity or to any intermediate heat desired,

A further object is to provide a burner whichmay be readily cleaned andwhich shall be of simple, cheap, and durable constructiori. A further object" is to provide a burner which shall be noiseless; obviatinga great ob- 'jection' to the majority of' burners of this class heretofore constructed: 1 I

A further-object is to provide means at the' top of the burner for retaining the heat in that part ofz thef burner for the purposeofvolatili- 'z a'tion, sued-means consistingin" an outer a'p of asbestos placed overtheouter' layer. or I I surface'of the cap of theburner: I i A further object is to providea burner of aconstructionwhich shall. provide a smoke less noiseless blue-flame burner adapted for use-inany stove or -to be placedupon a table and operated in a; room-without the use of a Stovepipe or aflue or maybe used as a lamp; 'for lighting purposes by the addition "of a; globe or large lamp chimney, or if desiredfto. use for heatinga room a heating-drum may? be placed-over the flame. v

A further objectis to provide means for regulating the draft of air through and around the flame. 1 f i I A further object is to provide suitable means for insuring the entire consumption of all smoke. 1 a

' after-appear from the detail Other objects and ends in'view will hereindescription of construction and operation. The invention consists in general in a hydroover the cup and having a cavity in its under toprOject into thevoil' in said cup, but termi- .nating above the bottom thereof, whereby the saidlegs orribs extend into the oil and heat the same, but donottouchany portion of said cup, and means for directing air into the cavity, a passage being provided between the cover and the-rim of the c'up for the escape of p air'an'd vapor. The inventionjconsists, further, in the pro vision, in connection with the vaporizer, of means for consumingfall smoke and effectuati'ng a complete combustion of the burning vapor, in novel means for regulating the draftvof air through ancl around theflame,

and'in the provision of such smoke c onsum- 7 mg. apparatus in form' to conveniently and readily receive a lamp-chimney for lighting purposes or a h'eating-drum for heatingspurposes. t

The invention consists, further, in the constructions and in-general and subcombinations of parts, all as hereinafter described and particularly pointed out in the claims,v andwill be more readily-understoodby reference to the'acoompanyi-ng drawings, forming a part of this specification, in which --;'Figure lfli s' 'aperspective view ofa hydrocarbon-burnerembod'yingmy invention.

Fig. V is a 'perfsp'ective viewof the cap or cover detached.

- Fig. "VI is a view' of one of my'burner s eq i ppedwith smoke-consuming apparatus and .a heating-drum, the burner proper and the heating apparatus being sh w-n' in longitudinal section. Fig. VII is a sectiTorija-l plan view on the line V11 VII of Fig. VII-'- As shown in the drawings, 2 designates a 55 carbon-burner comprising an open cup, means for supplying 011' to the cup, a cover arranged cup or bowl with an open top. Preferably formed integral therewith is a central pipe 3, providing a duct 4, leading upthrough the cup, and preferably cast integral with the lower end of this pipe is a second cup or bowl 5.preferably of a greater diameter than that of the cup or bowl 2. p

6 indicates a cover or cup above the cup or bowl 2, preferably havingaeoncavity 7 in its under side and with an outwardly -fl'aring flange 8 extending laterally beyond the rim of the cup 2. This cap or cover 6 is provided with a lug or projection 9 at the center of its under side adapted to fit into the upper end of the duct 4, by which means the cap 6 is suspended in place over the cup 2. The cap or cover 6 is provided with a rib or projection 10 at its apex,such projection having a direction crosswise of the cap for the purpose of indicating the position of the cap or cover over the cup 2, as hereinafter more fully set forth. In the under side of the capor cover 6 I provide a series of downwardly-projecting legs 11, preferably four in number and equidistantly spaced. These legs project down into the oil in the cup 2 and toward the bottom thereof, but do not touch the bottom. I have found that by thus arranging the legs so that they do not touch any of the metal of the cup the heat of the cover or cap 6 is communicated to the legs 11 and by them communicated to the oil in the cup 2, aiding in the heating thereof, and'that by preventing their coming in contact with any portion of the cup all possibility of their being cooled by any portion of the cup is avoided. I have also found that by thus suspending these downwardlyprojecting legs in the oil, but away from contact with the cup, all noise is eliminated from the use of the burner.

The cup 2 is provided with an inlet 13, into which the oil-supply pipe 12 is screwed, as shown.

In the upper end of the pipe 3 I provide a series of radial ports 14:, opening from the duct 4 into the chamber formed between the concavity of the cover and the cup or bowl 2.

I provide the lower cup 5 with a series of air-inlets l6 and provide within the cup 5, in connection with said inlets 16, a slidable damper 17 provided with perforations 18, by sliding which damper the inlet 16 and perforations 18 may be caused to register to admit air or may be wholly or partially closed against the admission of air in the cup 5 from the bottom, as desirable.

19 represents means by which the damper 17 may be moved.

20 indicates a lug or indicator upon the outer flange 8 of the cap 6. As shown, this indicator is in line with one of the legs 11 and indicates the position such leg will occupy with respect tothe inlet 13. By so positioning the cup that the leg 11 comes directly in front of the inlet the. oil is deflected around the cup openings 27, leading into the chamber.

and not permitted to come into contact with the pipe 3 until partially volatilized.

In Fig. VI the vertical wall 5 of the lower cup is not extended upward as high as in Figs.

I and II, and beyond the vertical wall 5 is a flange 21, an annular way being formed between the inner surface of the flange 21 and the outer surface of the wall 5, and in this way is mounted a slidable damper 17, corresponding with the damper 17 of Figs. I to IV, and provided with perforations 16, adapted to be registered with perforations 18 communicating from said way down below said lower cup or pan. The rim of the flange 21 is provided with a series of projections or legs 22, of which there may be any desired number and upon which the hollow uprights or supports 23 are seated. The smoke-consuming apparatus is supported on these columns 23. This means consists of an outer wall 24 and an inner wall 25, suitably connected and forming between them the smoke-consuming chamber 26. The inner wall 25 is provided with a series of Upon the inner surface of the outer wall 241 provide a suitable lining 28 of asbestos. The chamber 26 is provided at its top with a series of comparatively small outlets or openings 29. 30 indicates an upper cap which is seated upon the cap 6, being preferably provided with a socket, into which the projection or nub 10 of the cap 6 is inserted. I prefer to provide upon the upper portion of the cap 30 a suitable coating of material, preferably asbestos and fire-clay mixed to a paste and forming a suitable covering adapted to accelerate the reflection of heat outward onto the cap or cover 6. As shown in Fig. VI, the upper cap 30 has a convex bottom, the curvature continuing until the edge of the convex portion is substantially in line with the outer edge or rim of the cup 2, from which point the bottom of the cap 30 extends out horizontally toward the wall 25 of the smokeconsuming chamber. However, this horizontal portion 31 terminates a distance from the said wall 25, such distance being substantially equal or a trifle less than the width of the chamber 26. The horizontal portion 31 at its outer edge is provided with an u pw ardl yextending flange 32, forming a rim for holding the coating 27 in place. The horizontal portion 31 is also provided at its edge with a series of downwardly-projecting bars 33, which, in effect, form a grate for the purpose hereinafter set forth. 34 represents a draft-regulator, preferably in the form of an annular band of sufiicient width to provide the proper regulation of the draft to the burning vapor within the chamber formed between the rim of the cup 2 and between the caps 6 and 30. In practical use this regulator is made of much greater width in proportion to theheight of the burner than is shown in the drawings, so that when in the lower position, as shown in Fig. Vl, a large proportion of the open air-inlet between the bottom of the smoke-consuming chamber and the lowerpan or cup is closed. The inlet of air to the sides of the burner may be regulatedby change of position of-this regulator 34. This may beeffectuated by providing a series of steps 35 upon the periphery ofthe wall 24 and providing the regulator with projections adapted to be seated on any desired step,

thereby supporting the regulator at any desired height. 36 represents a suitable heater, or, ifdesired, a lamp-chimney may be be used in place thereof. The chamber 26 is preferon through the pipe 12 and maybe-allowed to fill the cup and in a measure flowover the rim thereof and "drip from the bead 21to the lowerpan or cup 5, thus diffusing the oil with the atmospheric air, and the samewill then be ignited, thereupon heating the extending flange 8 of the cover and also in a measure heating the upper cup. The cover 6 acts as reflector and reflects the heat'down upon the surface of the oil contained in the upper cu-p 2. The oil in the cup 2 reaches the-boiling- I point, and vaporrises from the heating and ,side of the flange 8.

= thus mixed with hot air, and the vapor is thus forced down and the commingled product n distillin g'oil, enters the cavity? of the cover or reflector 6, where it becomesmore highly heated, and then escapes downward and out-' ward through-the annular discharge 22 from between the rim of the cup 2 and the-under Cold air rushes into the cavity through the pipe or hollow stem 3 and becomes heated, forcing the vapor and hot air back down toward the surface of the oil The concave form of the cavin the cup 2. ity shown facilitates this action; ,The vapors which arise from the surface of the oil are passes out through thewopen passage ordischarge-slot 22, furtherheating the reflector as it burns. "The depending legs 11 apparently arrest for a time the downward flow of vaporfand hot air, and there results a' com trates the inwardly reflected rays of heat motion of these elements'and athoroughmixing of the same, and when said elements are; forced out by the draft of cold air from the pipe 3 and become ignited at the rim of the flange 8'there-results a'good flame without noise from the explosion of gases or otherwise. The dome shaped cover or heat reflector 6 becomes highly heated and concenupon-the vapors. contained inthe cavity and also refiectsthe heat down upon the surface of the oil in the cup.

7 The covering 15, of as-- bestos and fire-clay or other confining mate-' rial, serves to prevent the .radiation of heat outwardly from the'reflector or cover 6, causingan' increased reflection of the heat downward. j I

Inlpractical operation as soonas the flame is well started the operator will regulate-the oil-supply, so that the oil will not flow over the rim of the upper cup, and as soon as the oil in the lower cup is consumed the flame is then supplied wholly from the vapors" which rise from the surface of the oil in the upper cup and said oil is heated only from above, so that there is no danger of boiling over, and as the supply of oil is decreased to lessen the fire the surface ofthe oil in the cup lowers to a greater distance from the cover and less heat is applied to the oil and the flame becomes reduced in correspondence with the amount of oil supplied. I 1 Y I i To clean the burner,.the cover may bereadily lifted off, thus giving'access to the under side of the same and to theinterior of the cup.

'As the air-pipe 3 extends above the rim of the cup andopens-into theconcavity, the air isfthus inducted'up into the body of vapors in the dome and must flow down again in order to pass out from above, the cup. The, ports 14 are preferably so positioned in the air-pipe 3 with-respect -.to the inlet 13 that when aleg 11 is broughtoppo'site said inlet 13 the respective .legs 11, are opposite the ports 14. The air entering through the ports '14 comes in contact with the legs 11 creating a greater'commotion in the refractory heating-chamber formed between the cover 6 and the cup 2.

If 'desired,= the ports 14:, instead of being inthe form'of perforationsthrough the pipe 3, maybe in the form-of vertical slots extending from the top of the pipe down any desired distance.

In Fig. VI, 40 represents an overflow-pipe,

which I preferto provide in connection with. the lower-cup or pan and by means of which any overflow of oil may be carried off toa suitable receptacle. As shown, this pipe communicates into the chamber of the lower cup 1 through a boss 40, which extends somewhat above the bottom, of the pan, permitting sufficient oil to accumulate in thepan-for the purpose of generating. r In case by accident too much oil is permitted to flow into the cup 2 and dropinto the lower cup or: pan it is by this pipe 40 carried to a suitable receivingtank provided in-connection therewith. I

In Figs. I and II I have shown the cap or cover 6 provided with a coating 15,'consisting, preferably, of asbestos and fire-clay mixed to a paste and forming a casing or jacket on the outside of the-cap or cover, and have'shown the cap or cover 6 provided with a flange8, adapted to retain this casing or jacket in place. This casing or jacket serves as a protection to the cap or cover, preventing rapid deterioration. It is obvious, if desired, the

burner may be used without this casing or jacket 15.
